Eyewear comprising a frame having top, bottom and opposite sides defining a lens opening, each opposite side having lens engaging means, and a lens adapted to be removably attached to the frame to substantially cover the lens opening. The lens posseses translucent front and rear faces, opposite first and second side ends, and a first and second lens locking portions. The first lens locking portion is located at the first side end for cooperatingly engaging one of the lens engaging means at a first opposite side of the frame. The second lens locking portion is located at the second side end for cooperatingly engaging the lens engaging means at a second opposite side of the frame for locking the lens to the frame. The lens is flexible in a direction enabling distance variation between the first and second lens locking portions. Manual pressure exerted on the lens to flex it engages and disengages the locking portions with and from the lens engaging means. The invention is useful in many sports, where there is a need for wearing protective eyewear in order to avoid eye injuries. It is especially advantageous in sports where it is desirable to have the capability to replace eyewear lenses quickly. This may be necessary because of changing light conditions or simply because a lens may be damaged or dirty thereby impeding the wearer's vision.
